Start blending the pistachios onna food processor on high speed. You'll notice that the pistachios will become powdery and grainy.
Scrape down the sides and keep mixing for a total of two minutes.
Add the powdered sugar or date paste, and the salt.
Start adding the oil and depending on how thick you like to get you don't have to add too much and if you want it thinner just add more oil.
Put in an air seal tight jar and it should last up to a few weeks or you can leave it in the fridge for up to four weeks.
If the pistachio butter is warm, do not close it up. Let it cool down before closing the jar.
